Steve, The best analysis I can offer is that your mic configuration header may not be wired correctly. It is best to check it instead of relying on what someone has said about it.
Since this is your 1st K2, and you did not build it, I assume you are not familiar with how it all fits together. You must remove the front panel to get to the header. The process to get to the mic configuration header is to remove the top cover or KPA100 (6 screws). Next, check to see if it has the KDSP2 or KAFT2 installed (to the left, oriented vertically, behind the control panel) - if so, remove the screw located near the center of that board (if it is the KDSP2, you will have to remove the outer board first to get to the fastening screw - just pull that out of the header pins observing proper anti-static procedures). After removing the screw, you can pull the board out by moving it toward the rear of the K2. There are two screws holding the control board to the front panel - if you look down between the two boards, you will see the hex standoffs - remove the screws from inside the K2 (or 1 screw and 1 standoff if you had the KAF2 or KDSP2 installed). Now remove the 4 screws holding the Front Panel (located on the outside covers) and pull the Front Panel and its board straight out to the front. The mic configuration header is located on the back of the front panel near the mic jack. It takes more effort to put the process in words than to do it. Do it once and you should be a pro, it is not difficult. Compare the mic header wiring with the listing of common ham mics in the KSB2 manual. If you did not receive documentation with your K2, you can download the manuals from the Elecraft website as .pdf files. Be aware that many Icom mics have electret elements and need a resistor from 5 volts to the AF mic pin - this resistor is commonly soldered to the back of the mic jack if it is needed. You will have to determine the properties and pinout for your particular mic (it would be nice if they were 'standard', but alas, there is a large variety of differences). I can only help on the K2 side. 73, Don W3FPR > -----Original Message----- > > Im the proud new owner of my first K2. 3rd Owner (built by D Shipman) > sn 2110 :) > > quick question ? > > I have everything connected... > I have tried 2 Icom mics (previous owner said it is set up for Icoms and > sent an HM36) > I also tryed a Heil handi mic wired for Icoms... > > on a "Tune" it shows wattage out on the watt meter and tunes the antenna. > When I key the mic...it keys the radio but no forward power out...none > > I set the SSBA to Mic Gain 2 &3 and processor to 2,3,4 etc...still > nothing out > > _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
